[PATCH v2 0/7] Fix several issues in DTHEv2 driver

[T Pratham <t-pratham@ti.com>]

This series fixes a handful of independent and mostly benign till now
issues in the DTHEv2 driver which were flagged by bots and AI agents.
Except for the fourth patch in this series which was found in an
internal testing.

The Sashiko review on DTHEv2 hashing driver patch series v5 pointed out
some pre-existing issues which needed to be fixed.

One of the issues had already been flagged by kernel test bot and a fix
sent on the list by Mert:

I included this patch in this series with minor edits. Then the Sashiko
review page for this had more comments:
https://sashiko.dev/#/patchset/20260613085858.32580-1-mertsftl%40gmail.com
Overall this resulted in a bunch of fixes patches which would have
deviated the DTHEv2 hashing driver series had they been included with
it. So I clubbed them together in a new patch series which is this.
